I still don't understand why you don't understand your post. Your wife can't strip in the street. She could, I suppose, but she wouldn't make the money she would in a club, right? This is still very different from some band playing at a venue. You're comparing very different forms of entertainment. I've never had a blowie off the band, nor would I want or expect one, but I've rolled 10/10 out of the "dancers".
Because a hired employee is providing a service for the company. Having to pay to work is backwards. I don't know what you do for a living , but would you want to pay your employer for the privilege to work for them? It makes no sense. If you are contracted and are renting a space, sure. But a hired employee is on the payroll and part of the company at that point.
Also, I made a direct comparison between dancers and bands, based on my own personal experience and the conversation my wife and I were having. Even Bo seems to not know about this pay to play thing. Just seems kinda crooked, that's all.
